One-Minute Overview

Forged stainless steel block flange that closes a 2 inch flange joint.
Raised face, 150LB class, dimensioned to ANSI B16.5.
Corrosion-resistant forged body for demanding plant environments.
Serves as a permanent end cap or a temporary block.

The RF block flange, also called a raised face block flange, closes a 2 inch piping joint with a solid forged plate. Dimensioned to ANSI B16.5 in the 150LB class, it bolts onto standard weld neck, slip on and socket weld flanges of the same size and class. The raised face takes the usual 150LB gasket, and the forged stainless steel body resists corrosion in demanding environments.

At 2 inch this blind is easy to place at the end of a small header, at a future branch point, or across a valve during maintenance so the section can be opened safely. ANSI B16.5 dimensions make integration into existing piping straightforward, and the forged body holds the class without fuss. Choose the gasket for the medium and tighten the studs evenly in a star pattern to the gasket guidance. Because the body is forged, it keeps its shape through repeated openings and can be refitted after each job.

FAQ

Q1. How does the raised face perform at a 2 inch 150LB joint?

The raised face narrows the sealing area so bolt load concentrates on the gasket, which keeps the joint tight at class pressure. Dimensioned to ANSI B16.5, this 2 inch blind matches standard flanges of the same size and class and uses the usual 150LB gasket.

Q2. Where would I actually bolt this little blind?

Wherever a 2 inch line must be blocked or temporarily blocked: the end of a header, a future branch point, or across a valve while a section is opened for maintenance. It also works as a permanent end cap for a line being retired.

Q3. Two inches — is it just a washer with ambitions?

A washer that has to hold line pressure, ambitions included. It is forged rather than stamped, dimensioned to ANSI B16.5, and sealed on the raised face with the right gasket, so it does a real pressure-boundary job at a small size.

How long will production take?

Standard sizes are typically ready within 30 days, and in-stock items ship immediately. Larger or custom orders get a confirmed date per order, because the schedule depends on quantity, material, the bolt pattern you specify, and how busy production is at the moment you order.
